A total of 722 tickets were sold for the school play. they were either adult tickets or student tickets. there were 72 more stud
ent tickets sold than adult tickets. how many adult tickets were sold
1 answer:
S + a = 722
s = 72 + a
(72 + a) + a = 722
2a + 72 = 722
2a = 722 - 72
2a = 650
a = 650/2
a = 325 <== adults
s = 72 + a
s = 72 + 325
s = 397 <== students
